[0056] A shell 2 is provided to cover the button 1. An opening for exposing the button 1 is formed on the shell 2. The shell 2 surrounds the button 1 area, and a user can press the button 1 through the opening.

[0057] A disinfection structure is disposed at the opening and can move freely at the opening, and the disinfection structure can disinfect the entire key 1 area through free movement, thereby effectively reducing the volume of the disinfection structure;

[0058] The disinfection structure disinfects the key 1 during the movement to prevent viruses or bacteria from remaining on the key 1, thereby achieving the purpose of preventing virus transmission.

[0059] The keys 1 are distributed in a rectangular area, the opening is in the shape of a rectangle, and the disinfection structure moves freely along the length direction of the rectangle. On the premise of ensuring that the disinfection structure can disinfect the keys 1, the volume of the disinfection structure is reduced as much as possible to avoid interference with the keys 1.

[0060] The disinfection device further comprises a driving structure, and the driving mechanism drives the disinfection structure to move freely at the opening.

[0061] The driving structure includes a driving motor 3 and a transmission belt 4, the transmission belt 4 is arranged along the length direction of the opening, and the disinfection structure cooperates with the transmission belt 4 in transmission. Preferably, the transmission belt 4 is meshed with the output shaft of the driving motor 3, and the disinfection structure is fixed to the transmission belt 4, so that the disinfection structure is driven to move by the transmission belt 4 during the rotation of the output shaft of the driving motor 3.

[0062] The driving motor 3 can perform forward output and reverse output, thereby driving the driving belt 4 to move in two directions.

[0063] There are two transmission belts 4, one of which is in transmission cooperation with one end of the disinfection structure, and the other transmission belt 4 is in transmission cooperation with the other end of the disinfection structure, wherein the two transmission belts 4 have the same operating state, thereby ensuring the balanced reception of the disinfection structure, thereby performing translation at the opening.

[0064] The disinfection structure includes a main body 5 and a disinfection mechanism arranged on the main body 5, wherein the main body 5 is arranged at the opening, and the disinfection mechanism is arranged between the main body 5 and the button 1, wherein the main body 5 is fixed to the transmission belt 4 and can drive the disinfection mechanism to move to complete the disinfection work.

[0065] The disinfection mechanism includes a cleaning brush 61, and the cleaning brush 61 is arranged on the body 5. The end of the cleaning brush 61 away from the body 5 disinfects the key 1. The cleaning brush 61 slides over the key 1 during movement to complete the disinfection. Preferably, the cleaning brush 61 is a rolling brush, which can rotate to a certain extent during movement to increase the cleaning effect. In particular, the tangent direction generated by the rolling brush at the key 1 is opposite to the moving direction of the disinfection mechanism.

[0066] The cleaning brushes 61 are arranged in a row along the width direction of the rectangle to ensure that the cleaning brushes 61 can disinfect all the keys 1 .

[0067] The cleaning brushes 61 are arranged in two rows, and the two rows of cleaning brushes 61 are respectively arranged on the two edges of the main body 5 in the length direction of the rectangle, that is, in the moving direction of the disinfection structure, the surface of the main body 5 facing the key 1 has two edges, one row of cleaning brushes 61 is arranged on one edge, and the other row of cleaning brushes 61 is arranged on the other edge, so that during the movement of the disinfection mechanism in two directions, the two rows of cleaning brushes 61 can play a good cleaning and disinfection role.

[0068] The disinfection mechanism also includes a liquid storage box 7, which is arranged on the main body 5, and the liquid outlet direction of the liquid storage box 7 points to the button 1 and / or the cleaning brush 61. The liquid storage box 7 stores liquid (such as disinfectant) that can be used for disinfection and / or sterilization. When the disinfection structure moves, the liquid storage box 7 can move above the button 1 with the movement of the disinfection structure, and at the same time, spray the liquid stored therein onto the surface of the button 1 or the cleaning brush 61, thereby increasing the disinfection and sterilization effect.

[0069] The disinfection mechanism also includes a liquid storage box 7, which is arranged inside the shell 2, and when the cleaning brush 61 enters the shell 2, the liquid storage box 7 disinfects the cleaning brush 61. The liquid storage box 7 stores liquid (such as a disinfectant) that can be used for disinfection and / or sterilization. When the cleaning brush 61 enters the range of the liquid storage box 7, the liquid storage box 7 sprays the liquid inside it onto the cleaning brush 61, thereby completing the disinfection of the cleaning brush 61 and enabling the cleaning brush 61 to also have a disinfection function during the mobile cleaning process.

[0070] The disinfection structure has an initial position. When the disinfection structure is in the initial position, the liquid storage box 7 disinfects the cleaning brush 61, the button 1 is in a vertical plane, part of the shell 2 is at the upper part of the button 1, and part of the shell 2 is at the lower part of the button 1. When the liquid storage box 7 is arranged in the shell 2 at the upper part of the button 1, the shell 2 at the upper part of the button 1 constitutes the initial position of the disinfection structure. Similarly, when the liquid storage box 7 is arranged in the shell 2 at the lower part of the button 1, the shell 2 at the lower part of the button 1 constitutes the initial position of the disinfection structure, thereby ensuring that the disinfection structure can be disinfected by the liquid inside the liquid storage box 7 when it is in the initial position. In particular, when the disinfection structure completes the disinfection work, it automatically returns to the initial position.

[0071] The liquid storage box 7 is provided with a nozzle, and the spraying direction of the nozzle constitutes the liquid outlet direction of the liquid storage box 7 .

[0072] The disinfection mechanism includes an ultraviolet disinfection unit 62 , which is disposed on the body 5 , and the irradiation direction of the ultraviolet disinfection unit 62 points to the key 1 , and the ultraviolet rays generated by the ultraviolet disinfection unit 62 are used to irradiate and disinfect the key 1 .

[0073] There are multiple ultraviolet disinfection units 62, and all of the ultraviolet disinfection units 62 are arranged in parallel along the width direction of the rectangle, thereby ensuring that all buttons 1 can be irradiated by ultraviolet rays to achieve the purpose of disinfection.

[0074] The disinfection mechanism includes a cleaning brush 61 and an ultraviolet disinfection unit 62, both of which are arranged on the body 5, and the cleaning brush 61 disinfects the key 1 at the end away from the body 5, and the ultraviolet disinfection unit 62 is covered in a direction pointing to the key 1, and the cleaning brush 61 slides over the key 1 during movement to complete the disinfection. Preferably, the cleaning brush 61 is a rolling brush, which can rotate to a certain extent during movement to increase the cleaning effect. In particular, the tangent direction generated by the rolling brush at the key 1 is opposite to the moving direction of the disinfection mechanism. At the same time, the ultraviolet disinfection unit 62 disinfects the surface of the key 1 by ultraviolet irradiation, and double disinfection ensures the disinfection effect.

[0075] The cleaning brushes 61 are arranged in two rows along the width direction of the rectangle, and the two rows of cleaning brushes 61 are respectively arranged on both sides of the ultraviolet disinfection unit 62 along the length direction of the rectangle, so that the disinfection structure can achieve double disinfection effect when moving in two directions.

[0076] The irradiation size range of the ultraviolet disinfection unit 62 on the button 1 is 4-5 cm. When the disinfection mechanism moves at a certain speed, the button 1 can be irradiated for a certain period of time, thereby ensuring the disinfection effect.

[0077] The moving speed of the disinfection mechanism is in the range of 0.2cm / s-2cm / s, which avoids affecting the user during the operation of the disinfection mechanism, while ensuring that the ultraviolet disinfection unit 62 irradiates the key 1 for a sufficient time to ensure the effect. For example, when the moving speed is 1cm / s, the ultraviolet disinfection unit 62 can irradiate the same position of the key 1 for at least 5s.

[0078] The disinfection device also includes a control mechanism, which is electrically connected to the button 1 and the disinfection structure. The control mechanism is used to obtain a pressed signal of the button 1 and control the disinfection structure to perform disinfection work, thereby realizing automatic operation of the disinfection structure.

The interval t1 is to prevent the disinfection structure from causing harm to the user during the disinfection process.

[0083] Step S2 also includes:

[0084] Determine the moving speed V of the disinfection structure;

[0085] The pressed position of key 1 is obtained to form the pressed signal, and the distance S that the disinfection structure moves to the pressed position is calculated according to the pressed position, and the time period t2 that the disinfection structure needs to move is calculated, that is, the specific position of the pressed key 1 is determined, so as to calculate the distance that the disinfection structure needs to move from the current position to the position of the pressed key 1, and the time required for the disinfection structure to move is calculated according to the formula S=VT;

[0086] The disinfection structure is controlled to move in a first direction for a time period of t2 and then in a second direction for a time period of t2, wherein the first direction is opposite to the second direction, so that the disinfection structure is reset to its current position after disinfecting the pressed position, and the preferred current position is the initial position, so that the disinfection area of ​​the disinfection structure can be reduced as much as possible while ensuring the disinfection effect.

[0087] Controlling the disinfection structure to move along the first direction for a period of time t2 and then along the second direction for a period of time t2 also includes:
